Abstract

According to the data of scanning electron microscopy, in the plankton of the shallow-water eutrophic waterbody of the Ptichiya Gavan natural park (Omsk), located in the South of Western Siberia, 105 morphotypes of stomatocysts of Chrysophyceae have been identified and combined into 20 groups. The variety of morphotypes is significantly higher than the abundance of Chrysophyceae species (24 species) in this waterbody. The highest variety of morphotypes (64) is characteristic for ornamented stomatocysts. The maximum abundance of stomatocysts is observed in autumn, and the minimum is in winter. Unornamented stomatocysts with a spherical form without a collar are predominant. This data can be used for the paleolimnological reconstructions.

西西伯利亚南部水体中金藻科气孔形成的多样性和特殊性

摘要

根据扫描电子显微镜的数据，在西伯利亚西部Ptichiya Gavan自然公园（鄂木斯克）的浅水富营养化水体的浮游生物中，已鉴定出105种形态的金藻气孔囊，并将其合并为20种。组。在该水体中，形态类型的多样性明显高于金藻科物种的丰富度（24种）。形态最丰富的形态（64）是装饰性气孔囊的特征。在秋季观察到最大的气孔囊肿，而在冬季观察到的最小。球形，无领的未装饰气孔囊占主导。该数据可用于古湖泊重建。
